I have a transformer that will output 110v AC, and when I connect the Rectifier to it,... im still getting AC instead of DC, please help! what im i doing wrong?
The reason this is not a transformer, is because even when you dont load the output of the rectifier, there will be a current flow through the caps will still waste power in amount dictated by ohms law. a 100 and a 330uf cap in series is equal to a 76.74uf cap, which would have an impedance of 34.9ohms, ohms law says we are wasting 3.4 amps even when not loaded.
Yea I look forward to trying this with a bridge-rectifier and a 60+15uF AC-cap. Good safety to test circuits before dropping high-volts. Nice work with the caps, cool deal.
what you have done here is created a voltage divider with capacitors. The capacitive impedance for a 100uf cap is 26.52ohms at 60 hz, and for a 330 volt cap its 8.03ohms at 60hz.
Using the voltage divider formula and r2/(r1 + r2) we get 8.03/(26.52+8.03) = 0.232 times your input voltage of 120 gives an output voltage of 27.89, which is very damn close to the value you got, without knowing exact measurements.
im an electronics technician student. never gave thought about using caps as an AC voltage divider. good job

you can use a bleeder resistor to discharge the caps instead, no need to short them.

ac to a cell will produce heat. not much browns gas. great fro steam generation. check out my steam unit. i will post the video.

HELLO TV, There is obviously more than one way to skin a cat. Cheap way to vary voltage without a variac Nice work!
